Polymer fiber with improved long-term dispersibility

Polymer fiber with improved dispersibility The present invention relates to a polymer fiber with improved long-term dispersibility， a method for manufacturing the same， and uses thereof. The polymer fiber according to the present invention includes at least one synthetic polymer and a formulation present on the surface of the fiber， the formulation being carboxymethyl cellulose (CMC)， methyl cellulose (MC)， ethyl cellulose (EC)， hydroxyethyl cellulose (HEC)， hydroxypropyl cellulose (HPC)， methylethyl cellulose (MEC)， hydroxyethylmethyl cellulose (HEMC)， hydroxypropyl cellulose (HPMC)， ethylhydroxyethyl cellulose， carboxymethylhydroxyethyl cellulose， and It is a mixture of these. The polymer fibers according to the invention have improved dispersibility， and are therefore suitable for the production of aqueous suspensions， for example used in the formation of textile fabrics， for example nonwovens. The invention relates to a polymer fiber having improved dispersibility， a method for the production thereof and the use thereof. The polymer fiber according to the invention comprises at least one synthetic polymer and a preparation present on the surface of the fibers， said preparation comprising at least one cellulose ether selected from the group consisting of carboxymethyl cellulose (CMC)， methyl cellulose (MC)， ethyl cellulose (EC)， hydroxyethyl cellulose (HEC)， hydroxypropyl cellulose (HPC)， methylethyl cellulose (MEC)， hydroxyethylmethyl cellulose (HEMC)， hydroxypropylmethyl cellulose (HPMC)， ethylhydroxyethyl cellulose， carboxymethylhydroxyethyl cellulose， and mixtures thereof. The polymer fiber according to the invention has improved dispersibility and is thus suitable for the preparation of aqueous suspensions which are used， for example， in the formation of textile fabrics， for example nonwovens.
